Dual Inductor Based Two Input Two Output DC-DC Converter and its Analysis for DC Microgrid Application

Abstract

Two input two output DC-DC converters with two switched inductor structure are widespread in DC micro grid and Electric Vehicle (EV) applications with merits of solid structure, lower cost and high-power density. However, owing to the low voltage levels of the non-conventional sources used in the above applications, the significance of step up type DC-DC converters is so high. In this paper, a step up converter that is expert to deliver two different voltages at the output side from two different input energy sources is proposed as a new topology. It mainly contains two inductors for improving the voltage conversion ratio. Thorough analysis of converter has been performed with support of necessary equations and circuits. The performance assessment of DC-DC converter is done with simulation and experimental platforms and required waveforms are presented. A comparative study of the proposed converter is also fulfilled to signify the better features of the converter.
